<h2 id="下载jmeter-tps插件"><a href="#下载jmeter-tps插件" class="headerlink" title="下载jmeter tps插件"></a>下载jmeter tps插件</h2><p>第一步：下次Jmeter插件（<a target="_blank" rel="noopener" href="https://link.jianshu.com/?t=https://jmeter-plugins.org/wiki/TransactionsPerSecond/">https://jmeter-plugins.org/wiki/TransactionsPerSecond/</a>）</p>
<p>第二步：下载之后解压，将解压后的lib包覆盖到Jmeter目录下的lib目录</p>
<p>第三步：重启Jmeter，就可以看到有了tps的监听</p>
<p><strong>方法二：</strong></p>
<p>获取插件的最简单方法是安装 <a target="_blank" rel="noopener" href="https://jmeter-plugins.org/wiki/PluginsManager/">Plugins Manager </a>。 然后，您只需单击复选框即可安装任何其他插件。 </p>
<p> 下载 **<a target="_blank" rel="noopener" href="https://jmeter-plugins.org/get/">plugins-manager.jar </a>**并放入 <code>lib/ext </code>目录，然后重启 JMeter。   然后搜索插件： 3 Basic Graph 。 </p>
<p><strong>方法三：</strong></p>
<p>直接把 D:\01.GBase\2022GBASE工作记录\01.项目记录\00.技术\tpcc\jmeter 目录下的2个jar包放入<code>lib/ext </code>目录下即可。</p>
